WIRE-COUPLING.

No.'834,s44.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed September 18, 1903. Serial. No. 173,663.

lof Ohio, have invented certain new and useful Im rovements inWire-Oouplings, of

which t e following is a specification.

The object of my invention is to provide an improved coupling for the ends of Wires and my invention consists in the combinationand arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal section showing wire ends fastened together by a coupling embodying my invention; Fig. 2 a longitudinal section of the couplingtube; Fig. 3, a top plan view corresponding to Fig. 2, and Fig. 4 a transverse section on line 4 4 of Fig. 3.

The bore of coupling-tube A is inclined from each end to the axis of the tube, as shown in the drawings. Recesses a, having surfaces a inclined to the surfaces of wire ends B, are provided in either side of tube A. Locking-wedges O, provided with teeth c, are

y adaptedto take into recesses a, with teeth `c contacting with the surfaces of wire ends B. A central opening D is provided in tube A for the insertion or removal of lockingwedges C.

In use the wire ends B are drawn together and inserted in the bore of tube A, where they are locked in position by inserting wedges O in recesses a, as shown. The inclination of the bore of tube A to the axis thereof serves to increase the thickness of metal on the side of tube A where recesses a are located without unduly increasing the thickness of other portions of the tube-walls.

Thus ample strength may be obtained to resist the bursting effect of wedges 'C on the inclined surfaces of recesses a without making other portions of the walls of tube A unnecessarily heavy. It will be noted that the inclinations of the bore of tube A produce a corresponding bend in the wire ends B.

The strain on wire ends B tends to straighten l out this bend, and consequently throws the wire end forcibly against the toothed wedge C to insure a positive engagement with the wedge.

While I have shown and described the preferred construction for carrying my invention into effect, this is capable of variation without departing from the spirit of the invention. I therefore do not wish to be limited to the exact construction shown; but

What I claim as new, and desire to secure by Letters Patent, is-

1. A wire-coupling consisting .of a coupling-sleeve having a channel for .the reception of a wire, and having one wall thicker, than the others, and a locking device located between the wire and the thicker wall of the sleeve, substantially as specified.

2. A wire-coupling consisting of a couping-sleeve having a channel for the reception of a wire, said channel being inclined in the sleeve thereby leaving greater thickness of metal between the channel and the outer surface of the sleeve on one side than on the other sides, and a locking device located between the wire and the thicker wall of the sleeve, substantially as specified. l
